Viborg coach Jacob Friis insists they're capable of upsetting West Ham United.

Viborg and West Ham are meeting in a Europa Conference League playoff.

Friis said, "Yes, it probably won't be a walkover. A big and exciting task awaits, not only against a Premier League team, but also a team that a few months ago played in the Europa League semi-finals, and also did well in the Premier League last season.

"It is indisputably an insanely difficult task that lies ahead of us, but we are really looking forward to it.

"Our approach to the match will be the same as always, but of course without being naive.

"There are obviously some individual qualities in the teams that will be different, but our way of preparing and approaching the game will be the same.

"West Ham will probably do things with greater juice and power than we are used to, so of course we have to be sharp, and are aware that we have a huge task ahead of us.

"If everything goes as we hope, then we have 11 starters and a bench that performs at the top and at the same time a West Ham team that does not hit the day.

"We have to have luck in it and luck on our side, and if all that happens, it can start to look like something for us. A goal must be that the doubleheader is still alive after the first match."
